Solar Seal Leases 201,000 Square Feet at 40 Wisconsin Avenue in Norwich


40 Wisconsin Avenue in Norwich, a 229,000 square-foot manufacturing and distribution facility owned by an affiliate of The Grossman Companies Inc. of Quincy, Massachusetts, has been leased to Solar Seal Architectural LLC (Solar Seal) of South Easton, Massachusetts. Solar Seal will occupy over 200,000 square-feet of space for the next 12-plus years.

Solar Seal has been in business for 50 years. The company is known for their premium insulated glass units for medium and large applications. Their Norwich operation will be a state-of-the-art manufacturing facility with up to 100 jobs tied to its operation.

Solar Seal’s goal is to deliver “highest quality at largest size,” particularly 10-foot by 18-foot windows. Some of their recent notable projects include One Sixteen in Queens, NY; 1404 Ocean Pkwy in Brooklyn NY; The Nassau County Police Academy in Long Island, NY; and 425 Grand Concourse in Bronx, NY.

The Grossman Companies is a multi-generational real estate investment, development, and management firm with local roots dating back over 120 years. They own and manage an approximate 2.5 million square foot portfolio of commercial and residential properties concentrated in Southern New England.

An affiliate of The Grossman Companies acquired 40 Wisconsin Avenue in June 2020 with an eye towards the property’s long-term potential. New ownership made significant capital investments including a new roof for the entire building, a new parking lot, and aesthetic upgrades to the building’s interior.

Nicholas Morizio SIOR, CRE and Sean Kumnick of Colliers International represented both the landlord and the tenant. They have been engaged to lease the remaining 27,000 square-foot availability and to sell or lease the 11 acres of excess land on site.
